T0 all whom t may concern .f

Be it known that l, Fonnnsfr M. MAHAN, subject to the King of England, residing at Yuma, in the county of Yuma and State of Arizona, have invented a new and useful @il-Burner, of which the following is a specification.

\ rlhis invention relates to oil or hydrocarbon burners.

An object ot the present invention is to provide a novel oil burnerin which a perfeet mixture of steam and oil will be had prior to the issuing of the same from the burner mouth or discharge outlet.,

A'turther object isl to provide a unique oil burner including innerl and outer pipes for the separate conduction of steam and oil and provided with peculiar cooperating discharge outlets, which may be adjusted relatively to one another for the most effective operation of the device., f j v Another obfect is to provide a burner composed chiefly of plumbing fittings in order that the burner will be simple and cheap to construct, and at the same timewill be exceedingly efficient in serviCe.

`With the foregoing and other objects in view which will appearas the description proceeds, the invention resides in the. combination and arrangementl of parts: and in the details of construction hereinafter de* scribed and claimed, it beingunderstood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope ot' what is claimed, without departing from the spirit ofthe invention.

ln the drawings accompanying this speci.n iication and forming a part thereof, the pre- 'erred embodiment of m-y invention has been illustrated.

ln said drawings -Figure 1 is a view in longitudinal section of the improved oil burner, parts being broken away. Figs'.A 2, 3 and 4 are cross sections taken on the lines 2-2, L-3 and #iv-ii, respectively, of Fig. 1. Fig. 5 is a longitudinal section of a modified form of oil` and steamvnozzles. Fig, 6 is a cross section taken on `the line 6--6L of Fig. 5. Fig. 7 is a front elevation of the modified form of burner nozzles. Fig.4 8 is a cross sectional view of another modification.

ln carrying out the invention, there is provided a pair of concentrically arranged horizontal inner and outer pipes 5 and 6, respectively, connected to and communicating with the oil and steam supply pipes 7 and 8, respectively. 'lo this end, one end of a 'iT-coupling 9 is engaged to the inlet end of the pipe 5., and a plug or cap l11 is engaged to the other end of the T-coupling. rlhe oil supply pipe v7 is connected to the arm ofthe T-coupling and the pipes 6 and 8, are connected through the medium of the plug 11.

Outer and inner upstanding nozzles or pipes; 12 and 13 are connected to the outlet ends ot the pipes 5 and 6, respectively, by means-oi' outer and inner elbows 14 and 15, respectively. rlhe nozzles form extensions of the pipes 5 and 6. The upper or :tree ends oi the nozzles are threaded as at 16 and 17, respectively, and upon which are engaged the respectivel outer and inner capsV 18 and 19.,

Threaded upon the lower portion of the inner steam nozzle 13 is a 'flared annular' def'lector- 20, whose rim extends upwardly and outwardly away from the steam nozzle 18 toward the walls of the oil nozzle 12. Ports or apertures are provided in the nozzle 13 within the deiiector 20 for directing jets iiector so as to` impinge thereagainst and to be deiiected thereby upwardly within the nozzle 12.

rlhe steampipe 6 is provided in its top with a diagonal or inclined port or aperture 22 adjacent the nozzles for directing a stream or jet ot steam in a direct diagonal lineupward into the nozzle 12. One side of the nozzle 12 is provided with an arcuate transverse outlet slot or mouth 23, and the adjacent side of the nozzle 13 is provided with va similar slot 24- coperating with and relatively smaller than the slot 23.

In order to properly adjust and maintain in position, the nozzles 12 and 13, the cap 18 is` provided with a central threaded aperture 25 through which is threaded an adjusting or jam bolt 26.l The latter extends down upon and seats or iinpinges within a central depression 27 formed in the cap 19. @casting with the aforementioned adjusting means are three radial set screws or bolts 28 threaded through the walls of the pipe 5 and contacting with the inner pipe 6.

ln operation, it being understood that the supply pipes 7 and 8 are connected to suitable sources of oil and steam, respectively, the steam after passing through the pipe 6 and nozzle 13 will loe discharged through the outlet slot 24E in a fan or iilm-like stream,

ot steam against the inner walls of the de- Y i which will pass through the outlet slot or mouth 23 of the nozzle 12. The steam will also be discharged in a stream or jet through the aperture 22 diagonally upward into the nozzle 12, to atomize the oil, and thoroughlyk the suction created when'the steam is discharged through the slot 23 from the outlet slot 24 of the nozzle 13. The oil in entering the pipe 5, and surrounding the heated steam pipe 6, will become heated, to assist in the atomization of the oil before reaching the outlet. rlhe flame being of fan-like form, will spread throughout a considerable area, for increasing the heating effect and extent of the flame.

The steam nozzle 13 may be adjusted and held within the oil nozzle 12, by loosening the screws 26 and 28, and retightening the 'said screws properly for raising and lowering and centering the nozzle 13 within the nozzle 12. In this manner, should the nozzles 12 and 13 become disarranged, due to unavoidable reasons, such as the warping of the parts under the heat to which the device is subjected, the parts may be readjusted, in order that the burner will operate most effectively.

In the modified form of burner nozzles illustrated in Figs. 5 to 8, inclusive, outer and inner elbows 14 and 15 are provided, which are attachable to the outer 4and inner oil and steam pipes, respectively, as suggestedin Fig. `1. Outer and inner nozzles 12 and 13 are threadedly engaged to the elbows 14 and 15, respectively, and have the outer and inner heads30 and 31, respectively, at their upper ends. The heads 30 and 31 of the nozzles are provided with the coperating arcuate outlet slots 23 and 24', respectively. The head 30 is provided with a continuous flange or lip 32 surrounding the outlet slot 23', and the said lip is flared or fan shaped to spread the flame effectively, and to facilitate the operation of the burner. rIhe inner nozzle 13 is provided with upwardly inclined or diagonal ports or apertures 21 for the outletof steamvinto the Copies of this patent may be obtained for five cents each, by addressing the nozzle 12 for l agitating and atomizing the o1 In order to adjust and hold the nozzle 13 within the nozzle 12, a pair of adjusting screws 34 are threaded through the elbow 14 and have their tips engaging the inner elbow 15', and an adjusting screw 35 is threaded through the top of the head 30 and impinges against the top of the head 31, so that by adjusting the screws 34 and 35, the inner nozzle 13 may be adjusted and held properly within the outer nozzle 12.

In the form illustrated in Fig. 8, the lip 33 around the outlet slot, has its ends provided with the portions 34 which restrict the extent of the flame.

Having thus described the invention, what is claimed as new is l. A hydrocarbon burner comprising horizontal outer and inner fuel and steam pipes, respectively, upturned outer and inner nozzles connected to the outer and inner pipes, respectively, the nozzles having coperating transverse outlets, an adjusting screw carried by the upper end of the outer nozzle and bearing against the upper end of the inner nozzle, and adjusting screws threaded through the outer pipe and engaging the inner pipe.

2. A hydrocarbon burner comprising outer and inner fuel and steam pipes, respectively, and outer and inner nozzles connected to the outer and inner pipes, respectively, and eX- tending angularly therefrom, the said inner pipe having a diagonal aperture adjacent the nozzles for directing a jet of steam in a direct diagonal line into the outer nozzle.

3. A hydrocarbon burn er comprising outer and inner fuel and steam nozzles, respectively, having coperating outlets, and an annular flared deflector secured upon the inner nozzle, the inner nozzle having apertures within the said deflector for directing jets of steam against the inner walls of the deflector so as to impinge thcreagainst and to be deflected thereby.

In testimony-that I claim the foregoing as my own, I have hereto affixed my signature i'n the presence of two witnesses.

FORREST M. MAHAN.
